Description:
This catalogue is a new edition of the catalogue of the photometric
and absolute elements of close double systems by Svechnikov (ref 142).
After the appearance of this catalogue(1969), the numerous new data
concerning both photometric and spectroscopic elements of orbits of
the eclipsing binaries were published. The precision of determination
of the light curves of eclipsing systems is essentially augmented;
now, the light curves of eclipsing binaries are obtained mainly by
means of multicolour photoelectric observations; for a number of
systems,e extra-atmospheric observations from satellites and orbital
astronomical observatories are available. More details are available
in original.txt.

Note (1): The '*' indicates a note (see file notes)
the colon ':' a questionable value;
bracket ')' very questionable values (the original left bracket
has been removed)
Note (2): The mean fractional radius (or the small equatorial semi-axes
of ellipsoidal stars which are, within the limits of errors of
evaluation of photometric elements, practically equal to the mean
radii) relative to the orbital major semi-axis
Note (3): if the values of the limb-darkening coefficient of the
components are not equal, these are given in the notes (file notes)
Note (4): ratio of surface brightness found from the photometric solution;
if the geometric elements of the system obtained from several
different (but very similar) photometric solutions are averaged,
J1/J2 are calculated with the averaged values of the radii of
the components.
Note (5): Figures '1' and '2' designate the cases, when 2 essentially
different variants of the photometric solutions for the same
eclipsing system exist, and when we are not able to prefer one
of these cases (as a rule, however, only those photometric
solutions are given) which seem to be (in opinion of the authors
of this catalogue) the most realistic.
The data concerning the other photometric solutions (or corresponding
bibliographic references) are mentioned in the notes.

Note (1): The '*' indicates a note (see file notes)
the colon ':' a questionable value;
the bracket ')' very questionable values (the original left bracket
has been removed)
exclamation '!' is not explained in the "original.txt" file
Note (2): Mass-ratios found spectroscopically, from double-lined
spectroscopic orbit, are not accompanied by additional marks.
The values of q estimated by means of the so-called 'M-L method',
using the mass-function obtained from single-lined spectral orbit,
and assuming,that primary component satisfies the mass-luminosity
relation for the main-sequence-stars (see Kopal, ref 371;823;
Svechnikov, ref 142), are enclosed in brackets. The values of q
estimated by some other method, as well as averaged values oF
q, are accompanied by the asterisks.
Note (3):
The absolute bolometric magnitudes are computed using the
geometric and spectroscopic characteristics of the components
yielded in the previous columns; the stellar effective
temperatures given in Popper's (ref 1615) survey (and based mainly
on the scale of effective temperatures and bolometric corrections
of Hayes, ref 1623) are used.
Note (4): see Svechnikov, ref 142
Note (5):
Figures '1' and '2' indicate the cases, when 2 different variants
of the absolute elements are obtained (corresponding to 'case 1'
and 'case 2' of the evaluation of photometric elements or to 2
considerably different estimates of q). Also,in this column, the
number of the group for US-systems is indicated as well as some
other important remarks.
